I would like some opinions on does PWM matter? I sit in front of a screen ALL day and most nights. Does PWM matter to my eyes and ability to stay focused? I think my currentl monitor uses PWM (I tried the camera test, just roughly but I saw lines).Reply

Huh? Only you can answer that question. If you don't have trouble with a monitor with a PWM back lighting, then it obviously doesn't matter to you. Great article about it: http://www.prad.de/en/monitore/specials/backlight.... And they test PWM frequency with every monitor they get nowadays. :)Reply

Interesting. Discovered mine is at 240 Hz, which would explain why I get that flickering feeling (it's a cheap TN panel with an LED backlight, so not surprising). I'll have to try running it at higher brightness and see if that helps.Reply

The bottom line is that there are PWM-free panels now and they simply don't flicker.

A cheap way to stop PWM flicker is to turn a PWM monitor to full brightness. A TN panel can be tilted vertically to make the brightness more bearable. But, it's better, of course, to get a constant control backlight.Reply

You should probably try an include a couple of 120Hz LCDs like the Benq XL2410T, atleast in the input lag charts. I'd like to see how far behind IPS panels are, and of course, how close to CRT can a 120Hz LCD get.Reply

Actually they should use the Hazro HZ27WC for input lag comparison of 27" displays. It is also based on the LG panel but it's the ultra cut down cheap version with no scalars, only DVI input and no OSD at all! This means ultra low lag and is why I bought it. Check out the TFT Central review and input lag measurements below:

The question was really if using the 1:1 mode with non-native content instead of Full mode, so there was no scaling, would get around the lag hit of the scaler, but it does not do that. I'd like it if monitor vendors could make a lower lag mode, as some TV makers do with their game console modes, but I haven't seen one that has that effect yet.

120 Hz LCDs are on the list to do soon and get some better numbers on them.Reply

It's actually the first time I've seen a monitor claim to support resolutions larger than 1920x1200 over hdmi, so this is indeed very nice.Of course you'll need newest generation graphic card to support it too, but it's about time for monitors...Reply

Is there any word as to whether or not PLS will come in smaller sizes and resolution? 1080p? 1200p? And what about other PLS users? That 27" resolution is nice and all but doesn't fit well in the triple-monitor budget of mine. Would be nice if other companies will jump on the PLS bandwagon to add variety to the IPS and eIPS market.Reply

I think there may be an error in the processing lag/total response time graphs. The Asus is stated as 28.2ms on the processing lag chart and that looks roughly accurate on the total response time chart above it.

But, the Dell U2412m on the total response time chart looks to be about 16.5ms, but in the processing lag chart is listed as 29.5ms. Not sure if this is an error?Reply

Blah blah blah.Where are the next gen of monitors with ultra thin bezels like the apparent vaporware LG DM92?

We're in the era of multi monitors, where for many people bezel thickness isn't a major issue for work related stuff, but for others and especially gamers, the bezel just destroys the joy that could be had with multi-monitor gaming.

What is it that's holding back the next step? I just don't understand the issue given that we're seeing it at the extremes, phones and TVs.Reply

Myself I wonder when screens with higher pixel density will start to arrive. I don't expect higher resolution than 2560x1600 (no common interface to drive those resolutions exist today), but 2560x1600/1440 at maybe ~23-24" should be possible and very desirable. A 30" display is almost uncomfortable big.Reply

Well... most likely the next step is 4k monitors, just because they have the same aspect ratio as "normal" HD displays...But when they are affordable I can not say. But at least these are better than normal 1080 displays... Not much, but there is the difference.Reply

I don't really mind the 16:9 aspect ratio so much anymore; it's the 1080 lines of resolution that get me. I have a 1600x1200 monitor and a 1920x1080 monitor at work...the former is my primary monitor, 'cause those 120 pixels matter when coding or looking at spreadsheets. I'd swap the 1080p monitor for another UXGA one if I could (but I was lucky to office-scavenge the one I have :-P ).

If manufacturers wanna go 4K at a reasonable price, that's fine. Otherwise, I guess my next monitor purchase will probably be a U2711 (or another U2410).Reply

I think you forget to test about Responsiveness of pixel on this monitor. I think overdrive / response time compensation (RTC) technology is the best feature that cannot found in other high-end monitor.

PS. I'm quite surprise why your test result is far from another review. Do you use defect monitor?

TraceFree doesn't affect the lag time at all in my testing. I ran SMTT at all the various TraceFree settings and that doesn't change the lag at all. It does change the ghosting of the LCD which I did comment on, but it didn't change the lag in my testing.Reply

It's too bad the lag is so high, that is incredibly noticeable and you will feel it in every fps game you play, there is no covering it up, this is not a gaming monitor but a graphics/editing monitor, don't waste your money if you are a gamer. Scaler=FailerReply

I recently purchased a Viewsonic VP2770 that uses a PLS panel. I'm enjoying it more than the IPS panels I've had in the past. It has all the features that I was looking for such as non-PWM backlight, USB 3.0 hub, 27", 1440p, good selection of inputs, and a good stand. Too bad more places do not review it.Reply

Comparing input lag across the various inputs: DSub, DisplayPort, HDMI, and DVI inputs. If you suspect the multi-input board is causing an issue, is one input better/faster than the other? We often compare colour quality across Dsub and DVI, but let's check input lag, esp. DVI vs. Displayport.Reply

I always end up buying a Dell. Their monitors are just superb. Whether a cheap one for gaming or a great one for colour ediitng, the Dell monitors have great value. It is funny I always end up looking at all the tech out there and then I come back and buying one from Dell.

While I was reading this review I was wondering if it was going to be better and cheaper than my Dell 27"... maybe some new competition, after all ASUS make great stuff. But no.

BTW, you can always find discounts on Dell monitors if you don't have to buy them right away. I have always managed to get mine on huge discounts. Gotta love it!Reply

As luck would have it I had the horizontal sync chip in my trusty 1920x1200 Hanns-G 28" go out on Monday. So I needed a new display. The catch was that I wanted a higher resolution than a 1080P monitor. And this Asus seemed like the best compromise between resolution and price. We'll see how good it really is shortly...Reply
